RADIOLOG.

Application led .Tune 11,

An object of the invention is to provide a convenient and easily consulted record of radio broadcasting stations, so that the location of any station can be quickly determined when the designation of the station is known. Also, so that the wave length and the dial setting required to attune to any desired station may be readily obtained from the record made in the space provided from`previous observations.

The radio log of the present invention may serve to record in conveniently accessible manner other information as to the broadcasting stations than specifically indicated in the drawings illustrative of it, and referred to in the specifications'.

With reference to the accompanying sheet of drawings Fig. 1 sho-ws a front view of the radio log.

Fig. 2 shows the rear view of the radio log, when folded. y

Fig. 3 shows a side view of the radio log wherein it is set-up in its erected position.

The circular disc of cardboard 5 revolves about the eyelet 6 as' a lpivot. The eyelet 6 passes through the mounting cardboard member 7 and is flangedat 8 on the front and rear to retain it in place. The mounting member 7 is creased along the lines 9 and 10 so that the portion A of the member 7 may be swung towards the front and then about the dotted line 9 as an axis, so that the edge 14 of the portion lA will just overlap the line 15. When the. portion A is opened into the position shown in the Adrawing Fig. 1, a map of the United States, in the illustration) will be displayed. This map may occupy the space between the lines 15-16-17-18. Reference to the mapwill therefore require opening or swinging the portion A outward.

A tab.20 is designed to register with the slot 21in the mounting cardboard member 7. Of course, any other manner of securing or fastening'. the free edge of the portion A to the member 7, of which it is a part, along the v edge l5 may be adopted.

A rear portion or flap 25 made integral with i the member 7 and folded along the line 10,

or made separately and hinged on the line 1G is shown in Fig. 3-in its extended position. It iscalso shown in Fig. 2, but in its folded position, flat against the disc 5. A hinged tongue member 26 whichmay be a portion of the cardboard forming member 7 is adapted to protrude through the slot 29 in the portion 1926. Serial No 115,203.

25. The shape of the member 26 is defined by the dotted lines 31 in Fig. 3, showing the at an angle. y

A complete circular opening is cut out of the member 7 with 'the hinge ory folding line 10 as a diameter so the line 35 defines the half of the circular opening visib-le from the front and the line 36 defines the half of the circular opening visible from the rear.V

The circular disc 5 has a diameter larger than the distance between'the lines 7 and 9, and the distance between the eyelet 6 and the line 10 is less than the radius of the'disc 5, so that the disc 5 shows a chord of the circular disc 5 at the top and the sides beyond the outer top and side edges of the member 7 when the portion A is,folded in, which provides a convenient `manner of manually rotating the disc 5.

The circular disc 5 is laid off into segments 36 to 44 over its entire area, preferably, though not necessarily of equal angular dimension. Eachsaid segment will serve to record the data with reference to one or more A broadcasting stations; the illustrations showing the data of two stations for a segment.

In addition to the radial lines for defining the segments of'the disc 5 concentric lines are made to divide the segments so that in additionto the station designations, station location and wave length data, spaces for the dial settings for the corresponding station or stations will be below the station designation.

The rear side of theldisc 5 has segments laid olf so that theymay be used to record stal tions and data with respect to'each as on the front side of disc 5, and which data may be added from time to'time after the disc 5 has been printed by way of showing the segments and concentric circles referred to,.as well as the positive .station data generally applicable.

quently consulted ,or the station paying for s ecial advertisinffma be distinctive, so as to attract particular attention. This may be done by coloring. Moreover,more than' one stationmay be thusrendered more conspicuous for advertising purposes.

It will be noted that considerable space will v,

be available on the blank faces of the radio log whichmay be used forthe display of advertisements, and therefore the invention is particularly adapted to advertising objects.

While the radio log of the present invention has been deseribedas being made of card board, it Will be understood that it may be made of any other suitable material; sheet metal covered With paper, for instance, Without departing from the spirit of the invention. Also, the yinvention may be modified from that specieally shown inthe drawings to broadly illustrate the invention, Without departing from its scope, in vieW of the subjoined claim.

Iclaim:-

In a device of the character described, a

mountingv formed of a suitable material hinged to form front and rear upstanding sections which may be opened gable shaped, a revolvable .circular disc mounted parallel to and on the rear of the front section, a segment cut out of the front section along the hinge, the disc mounted so its periphery eX- tends above the hinge line so that a larger segment of the disc is displayed through the segment of the mounting than the segment area of the segment removed from the front section of the mounting.

In Witness whereof, I hereunto subscribe my name this 5th day of June, 1926.
